Vacuum Drops

Except for Eurovac II 4-man budget systems and detail systems (which use PVC pipe), we use 14- and 16-gauge galvanized metal thin-walled tubing. The fittings have expanded ends that fit over the end of the pipe and heat-shrink tape holds everything in place and assures an airtight seal. Metal pipe is preferred because static electricity which can cause static shock does not build up in metal pipe. When PVC pipe is used in a dust extraction system, we provide grounding wire for grounding the pipe.

The pipe is graduated from 2" at the end of the runs to 3" at the pump on Eurovac I and Eurovac II Central Systems, and from 6" at the pump on most Eurovac III systems, and up to 8" at the pump on the largest systems. As the piping gets closer to the pump, larger diameter pipe is required to accommodate the CFM from the “feeder” branches. In general, 2" pipe will accommodate two technicians sanding and 3" pipe will accommodate five technicians sanding, while maintaining the required airspeed to move the dust through the pipe.
